When I look at my profile I can clearly see an entry that reads
"May 5, 2018, 5:15 am Store Purchase MC 3,000"
Which is definitely after and before Nov 14th 2017-Nov 13th 2018.
If it helps at all, it was MC purchased directly through the official website as well, not through Steam.
Edit:
The issue has been fixed and it says I'm qualified now, whether it was just being slow to update or the issue was fixed directly. Thanks!
